There's no threading there. That's just sorting by subject with some bogus
scaffolding on the left-hand-side.

Not what is set in Mozilla, nor does it look the same if I DO sort on subkect.

In particular see how the "ACL to reject spam" and MailScanner threads
have a structure that your screenshot doesn't show, and how the structure
of various threads has been flattened by your replies.

True - but even with a 1400-wide screen, that is what I would want anyway.

Sub-branching ad infinitum may be technically correct, and certinly useful in an
environment where side-issues fell into clear categories, (Groklaw, maybe?) but
for most technical support lists the differentiation is not worth the cost of
the back-and-fill navigation.

Thanks. Working on that now.

Funny to see my own post hilighted in there. Does that mean you were
just about to post an answer to my question? :-)

Best regards,
Martijn.

Nicer 'strokes' than that.

It means you posted something novel or of more value than average that I want to
look into in more detail when time permits.

Mssrs. Finch and Hazel get the lion's share of those flags.

In this case it was a chance to compare my dormant PostgreSQL code with your
in-production MySQL code.

Presently we do not permit autoreply, and no user has ever missed it, so 'later'...

Why are you stripping In-Reply-To and References and so forth anyway? I
can't immediately imagine a reason for doing it.

Well - your very own post is a good example of a reason to cut down on
parasitical headers:

Again, I think you're mixing some things up here. If the 400 odd bytes
of X-Header content offends you, you can feel free to strip them out.
X-Headers are user or site specific, arbitrary, and irrelevant.

Standard headers like References (see how there's no X- prefix?) are
not, and should be left in place. That was the point of this
discussion.

You hit reply, your MUA automatically puts the Message-Id of the message
you are replying to into the In-Reply-To header, and adds it to the
References header.
(At least that's what I think what happens, without having read the
relevant RFC, it seems to me the natural and logical way...)

By hitting reply, the message should never be shown in another thread,
unless your newly created message has no In-Reply-To, in which case
other's MUAs have to solely rely on the Subject, which you could have
changed.

Thanks - but that is exactly the sort of artistic but useless eye-confusion I
need to avoid, and the primary reason I use threading ONLY to check the point.

Why would I want things to walk off to the right side of the page when the
subject already says all one needs? And pure descending date order is even
faster to read.

This is not source code.

Moz MUA does *preserve* these if present, a view source show it so, anyway.
Haven't looked at how it manipulates them, as we do the header stripping in an
Exim transport. Moz DOES have a filter that moves incoming list traffic from
inbox to into a local folder, but that alters neither headers, body, nor
attachments.

That's true if a subject were changed.

But the original situation arose when creating a NEW subject, not on a reply.

That should have become a new thread if based on the unique message-ID my MUA
would have created - transformed on the way back out to the References, etc.

What seems to have happened instead is that the mesage-ID was new, but also that
prior headers were left over. Perhaps in the composer's buffer from an earlier
post that *was* a reply or an aborted one.

That WOULD 'steal a thread'.

If that happens again I'll know where to look.

Well, tastes obviously differ. I usually don't even look into the
message list pane when reading a mailing list. With the keyboards
shortcuts (n, b, f, m in TB) it's quite easy and convenient to follow a
discussion. You might not need that if your memory is better than mine
(which is not the best).

Quote:

Neither is a book's table of contents or other things which use
indention, but still they use (often long before somebody spoke about
source code). Because it's a fast way to conceive context, without
having to use brain processing time for parsing words.

Anyway, this is not the right place to discuss that, maybe if we push
the topic more into the "don't remove headers without good reason"
direction". :)

Of course they are.

There is no such thing "thread stealing". What you're doing is just
*break* threading. Either by replying to messages you don't want to
reply to, or by removing Thread-Headers.

Bill has made it clear on multiple occasions that he believes that if you
don't do things his way, you're obviously wrong. See also long and rambling
threads on iptables, and on databases for auth and everything else that he's
been involved in.

If he doesn't want threading, why should he care if he breaks it for everyone
else.

Cheers

Not straightforwardly, I think. You can add a redirect router before your
smarthost router which grabs the addresses and uses :defer: to hold them
on the queue.

I thought about this... but how can i stop this defer ?

Probably with option "-D" and a macro as a condition? Work this new
macrodefinition only at one programm run if exim4 works as a deamon or
forever till the exim4 deamon stops?

The reason is we have in germany a few ISPs they need a break of e.g. 15
min. between connections of each user :-(

Check the queue_only_file option, probably you can 'basteln' something
using it.
